WALDENT Airotor User manual

A supply of dry, clean and uncontaminated compressed air must be provided. Dirty and moist
air leads to a premature deterioration of the ball bearings. The turbine needs a drive pressure
of 2.2 bar for operation. Lubricate the instrument before using it for the rst time.
The instrument must be coupled to a 2-hole Borden hose. Verify the connection of the ducts
of the instrument with those of the tubing, join them on and screw the xing nut by using
only ngers.
• Do not use an unqualified bur.
• Diamond bur shafts should follow the demands of ISO standard diameter of 1.59 - 1.60mm.
• Do not use a bent, damaged, or a short handle bur.
Bur Specications
For LED - The air ows into the built-in micro-generator, converting the kinetic energy into
electrical energy for LED lights. The discharge of airow through the motor gives the
high-speed rotation cutting eect.
For Non LED -The discharge of airow through the motor gives the high speed rotation
cutting eect.
• Operating pressure: 0.25MPa - 0.3MPa (0.3MPa
preferred ).
• Rotation Speed: 350,000 rpm for Super torque
head & 280,000 rpm for standard head.
• Borden 2-hole connection
• Air consumption: 55L/min
• Noise ≤ 60db
• Operating pressure: 0.18MPa - 0.25MPa.
• Rotation Speed: 350,000rpm for Super torque
head & 280,000rpm for standard head.
• Borden 2-hole connection
• Air consumption: 34-37Nl/min
• Noise ≤ 60db

Connection of Units
Screw type chuck (conventional chuck)
Bur removal: Mount the chuck wrench with the knurled knob pulled out. Push the knob into the head and make a ¼
turn in the counter- clockwise direction. Bur is ready to be removed (do not turn the knob more than a ¼ turn).
Bur mounting: To mount a bur, turn the knob in the clockwise direction with the knob pushed into the head.
Push type chuck
Bur removal: Press the push button in the head cap with tip of thumb to click, and remove the bur.
Bur mounting: Insert the bur into the head until it stops (1-2mm deep approx). Press the push button and further insert
the bur all the way into the head until it stops.
Cautions
Mounting and Dismounting burs
• Do not run the handpiece with the bur not fully inserted; bearings may fail prematurely due to poor bur concentricity
and resultant vibration.
• Never run a handpiece without a bur.
Cautions
• In case of cutting procedures having heavy vibrations such as in crown removal, there may be a case where it
becomes difficult to remove the bur. In such a case, pull out the bur with pliers while pushing the push button with
the wrench.
Cautions
• Do not exceed the recommended airpressure. This is important to prevent higher
speed which could causes breaking of the bur and premature bearing failure.

• Uncouple turbine from hose. Remove mill or diamond bur.
• Clean up the external part using 70% hydrated ethyl alcohol or any other disinfecting agent without having ammonium
or acid basis or chlorine.
• Do not immerge the handpiece in disinfection baths.
• Lubricate the turbine before each sterilization cycle. Handpieces which are not subject to a sterilization process must be
lubricated before each work cycle (in the morning, at noon, and evening).
• Improper care and lack of maintenance may lead to a premature wear and failure of the handpiece. Sterilize the
handpiece and bur changer in autoclave up to 135˚C. Autoclave for 20 minutes at 121˚C and 15 minutes at 135 ˚C;
withdraw handpiece from autoclave after the sterilization process is over.
